For longevity the older HP LaserJets were legendary.
I remember working in my early IT days and even in a busy office the only faults seem to be when a used put rubbish quality paper and caused jams. Maybe the longevity is related to them having print engines made by Canon.
My own colour LaserJet must be around 15 years old now, only annoyance is when it decides to do it's automatic & noisy cleaning cycle at 2am!
Toner cartridges are expensive but last for thousands of pages and don't dry out like inkjet so cost effective in the long run.
